Abstract
The utility model relates to a firefighting compression joint pipe fitting for composite pipes, comprising two adjacent composite pipes and two outer pipes. The outer pipes are sheathed on the external surface of the joint of the composite pipes. Besides, the two composite pipes and the outer pipes are connected together by clamping and pressing the external walls of the outer pipes, and high temperature sealing elements are provided between the outer pipes and the composite pipes. Compared with the prior art, because of the high temperature sealing elements which are provided between the outer pipes and the composite pipes, when a fire hazard occurs, though the temperature of the scene of fire is very high, seal failure of the joint of the adjacent two composite pipes can not occur, and the fire-fighting system can work normally. The hidden danger of serious fire accidents owing to the delay of fire extinguishing occasion is eliminated.
Description
Technical field
The utility model relates to the plurality of compound pipe by the pipe fitting that crimping links together and uses, and is specially a kind of fire-fighting with composite pipe pressure-connected type pipe fitting.
Background technique
Composite pipe is a kind of novel composite pipe, its combination property is very superior, give full play to the excellent properties of composite pipe and make composite pipe penetration and promotion application rapidly, must adjacent two composite pipes be connected mode safe and reliable, simple and convenient, with low cost.Existing Placement preferably is to adopt the Placement of pressure-connected type, but common pressure-connected type Placement is not provided with resistant to elevated temperatures seal arrangement in the joint, therefore will have common pressure-connected type composite pipe now and use with regard to cisco unity malfunction as fire-fighting.Because during breaking out of fire, the temperature of scene of fire is very high, may make the joint seal failure owing to high temperature, the connection of adjacent two composite pipes is destroyed, causes the fire-fighting system cisco unity malfunction, incurs loss through delay fire extinguishing opportunity, causes serious fire accident.
The model utility content
The purpose of this utility model is to consider the problems referred to above and provides a kind of high temperature resistant, fire-fighting that still can reliable sealing under high temperature environment such as breaking out of fire with composite pipe pressure-connected type pipe fitting.
The purpose of this utility model is achieved through the following technical solutions: it includes adjacent two composite pipes and outer sleeve, outer sleeve is nested with on the outer surface of composite pipe junction point, and press the outer wall of outer sleeve to make two composite pipes and outer sleeve realize being connected by card, between outer sleeve and composite pipe, be provided with the refractory seal element.
Refractory seal element between above-mentioned outer sleeve and the composite pipe can be high-temperature resistant seal ring or refractory seal glue.
Above-mentioned high-temperature resistant seal ring can adopt two-layer copper sheet therebetween thermal insulating material to constitute.
Compared with prior art, the beneficial effects of the utility model are: owing to be provided with the refractory seal element between outer sleeve and composite pipe, therefore, during breaking out of fire, although the temperature of scene of fire is very high, high temperature can not make the joint seal failure of adjacent two composite pipes, fire-fighting system energy proper functioning, eliminate delay fire extinguishing opportunity, caused the hidden danger of serious fire accident.
